1. 11. A New Shoulder for the THOR Dummy Intended for Oblique Collisions

   Författare :Fredrik Törnvall; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Shoulder; Shoulder range-of-motion; Volunteers; Kinematics; Biofidelity; Post Mortem Human Subjects; THOR; Crash test dummy; Oblique collision;

   Sammanfattning : Offset and oblique frontal car collisions represent a type of crash in which severe and fatal injuries frequently occur. This indicates the importance of having protective systems in vehicles for these types of collisions. LÄS MER

3. 12. Towards a human body model for prediction of vehicle occupant kinematics in omni-directional pre-crash events

   Författare :Emma Larsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pre-Crash Manoeuvres; Shoulder Muscle Control; Active Human Body Model;

   Sammanfattning : As the vehicle fleet becomes more equipped with crash avoidance systems, the proportion of crashes preceded by evasive manoeuvres is expected to increase. In an evasive manoeuvre, occupant position and posture can be influenced by the induced loading. Therefore, there is a need to predict the occupant response from evasive manoeuvres. LÄS MER

4. 13. Towards improved motorcycle helmet test methods for head impact protection : Using experimental and numerical methods

   Författare :Shiyang Meng; Svein Kleiven; Peter Halldin; Mazdak Ghajari; KTH; []
   Nyckelord :Head Injuries; Helmet; Injury Prevention; Motorcycle; Test Standard; Finite Element Method; Applied Medical Technology; Tillämpad medicinsk teknik;

   Sammanfattning : Head injury is the leading cause of death and major trauma for users of powered two-wheelers (PTWs). Helmet use can prevent and reduce head injuries when a crash is inevitable. However, today’s motorcycle helmets do not protect equally against all types of head injuries. LÄS MER

5. 14. Improving the Evaluation Process for Active Safety Functions

   Författare :Mikael Ljung Aust; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Situational Control; Advanced Driver Assistance Systems; Safety Benefit Assessment; Driver Behavior Analysis; Active Safety Systems; Crash Causation Analysis; In-depth Crash Investigation;

   Sammanfattning : The general aim of the present thesis was to improve key steps in the procedure for functional, formative evaluation of Advanced Driver Assistance Systems (ADAS). Five unresolved theoretical and empirical issues were identified and addressed. LÄS MER

7. 15. The role of forensic epidemiology in evidence-based forensic medical practice

   Författare :Michael Freeman; Anders Eriksson; Maurice Zeegers; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; forensic epidemiology; forensic medicine; probability; traffic crash; autopsy; logistic regression; Bayes´law; Forensic Medicine; rättsmedicin; Forensic Medicine; rättsmedicin;

   Sammanfattning : Objectives This thesis is based on 4 papers that were all written with the same intent, which was to describe and demonstrate how epidemiologic concepts and data can serve as a basis for improved validity of probabilistic conclusions in forensic medicine (FM). Conclusions based on probability are common in FM, and the validity of probabilistic conclusions is dependant on their foundation, which is often no more than personal experience. LÄS MER
